<A NAME="configure"><B><FONT SIZE=+3>C</FONT>HANGES IN THE SOFTWARE CONFIGURATION:</B></A>

<UL>

  <li> Updated to use Automake 1.12.4.  Avoids security problem with
  'make distcheck' (CVE-2012-3386).

<A NAME="libtiff"><B><FONT SIZE=+3>C</FONT>HANGES IN LIBTIFF:</B></A>

<UL>

  <li> Various memory buffer access fixes.

  <li> Fix handling when writing RGBA jpeg compressed imagery
  (<A HREF="http://trac.osgeo.org/gdal/ticket/4732">http://trac.osgeo.org/gdal/ticket/4732</A>).

  <li> Fix to work properly with IJG JPEG 7+.

  <li> New functions TIFFFieldTag(), TIFFFieldName(),
  TIFFFieldDataType(), TIFFFieldPassCount(), TIFFFieldReadCount(),
  TIFFFieldWriteCount() to use as external accessors for the opaque
  type TIFFField.

  <li> Fix bug rewriting image tiles in a compressed
  file (<A HREF="http://trac.osgeo.org/gdal/ticket/4771">http://trac.osgeo.org/gdal/ticket/4771</A>).

  <li> Add TIFF/FX tag support in libtiff.

<A NAME="tools"><B><FONT SIZE=+3>C</FONT>HANGES IN THE TOOLS:</B></A>

<UL>

  <li> tiff2pdf: Fail when TIFFSetDirectory() fails.  This prevents
  core dumps or perhaps even arbitrary code execution when processing
  a corrupt input file (CVE-2012-3401).

  <li> tiff2pdf: Fix two places where t2p_error didn't get set after a
  malloc failure.  No crash risk AFAICS, but the program might not
  report exit code 1 as desired.

</UL>
